looks, and particularly pertains to n lock in which the operation of thekey vtherefor is Controlled by e Coin.

It is the object of this invention to provide 'ii Coin-Controlled look,by ineens oit which the latch bolt ot the lock will be prevented frombeing operated nntil the deposit of A proper token, and which is soConstructed its to admit of the key being withdrawn or thrown only onthe deposit of' zt proper Coin or token.

Another object is to provide n .n zittaoln ment of the above ellnrznterwhich is adept ed to be mounted on the face or esentcheon plete of thelook Without necessitating any `while another Coin is already in thepocket.

plate 9 mounted on' its lower end. rlhis plate has a Vertical edgeparalleling the outer edge of the arm 5 which abuts against the pin 8.The pins 8-8 thus securely hold the lower end of the arm 5 againstsidewise movement, but permit of its being oscillated by the rotation ofthe platei2, as will be` later described. The inner edge pf the lowerend of the arm 4 is designed to contact the pin 8 and is heldthereagainst by means of a plate spring 10, mounted on a bracket 11carried on the escutcheon plate- A, which spring bears against a pin 12mounted on the arm 4. rllhe pin v8 thus serves to limit the inwardmovement of the arm 4 and also limits its downward movement, whenactuated by the plate 2, by

l plate spring 10.

lao

reason of its engagement with a shoulder 13 formed on the arm 4. It'willbe observed that the arm 4 may be rocked ,outwardly away from the pin 8in opposition to the Mounted on the lower end of the arm 4 xis aninwardly extending plate 14, which projects over the lower end of thearm 5 and forms a coin slot between the lower ends` of the arms 4 and 5,into which the coin maybe inserted through a slot 15 formed in theescutcheon A. A coin deposited in the slot 15 is designed to come torest upon p a shoulder or abutment 16 formed on the 'inner edge of thearm 5 where it is sup- 13 so as to prevent t-he plateQ being rocked bythe key E sutliciently far to allow the latter to be disposedv in itsvertical position in relation to the keyhole 3. By thisconstruction thekey E is prevented from being withdrawn from the lock and also blockedagainst movement, thereby preventing the operation of the bolt B.

In the operation of the invention when it is desired to ythrow the boltB and withdraw the key E, a token of a certain diameter or denominationis vdeposited in the slot 15, where it comes to rest upon the abutment16 between the lower ends of the arms 4 and 5, as before described andas shown in Fig. 4.' The shoulder 13 being spaced a short `distanceabovethe pin 8 will admit of a limited downward movement of the arm 4and a consequent slight rotat-ion of the plate .2. This movement 'of theplate 2 is effected by turning the key E, after Athe coin G isdeposlted, 1n such -a manner as to move the arm 4 in a downwarddirection and the arm 5 'in an upward direction. 'The upward' movementof the arm 5, carries the coin Gr therewith so as to bring its upperedge into contact with the lower edge of the coinpusher 17 on the? arm4. The downward movement of the arm 4 causes the member 17 to engage thecoin G and move it downwardly in oppo-sition to the arm 5, causing it topress against the abutment 16- and force the arm 4 outward away from arm5, as indicated in dotted lines in Fig. 4, so as to 'cause,the shoulder13 to clear the pin 8. This will admit of a continued rotary movement ofthe key Ey and the plate 2, so as to throw the bolt B into lockedposition and dispose the key E in t-he vertical position and admit ofits being withdrawn from the lock. In thuslocking the bolt, arm 5 movesup and arm 4 down. The coin. on passing over the abutment 16 falls upona stop shoulder 18 on the inner edge ofthe lower end of the arm 5, whereit comes to rest with its opposite edge against the inner edge of thearm 4. The coin G in passing over the abutment 16 releases the lower endof the arm 4 so that it moves inwardly by the action of t-he spring 10to throw the pinv 8 into engagement with a V-shaped notch 19 formed onthe inner edge of the arm 4. Formed inthe escutcheon plate 'A isaperfoi-ation 20 which registers with a similar perforation 21 formed inthe plate 9, when the arm-5 is in its uppermost position, so

g that the coin G, when resting upon the shoulder 18 as shown in Fig. 5,may be observed through the escutcheon plate. The coin G in movingdownward passes below the pin 8, as "indicated in dotted lines in Fig.5, where it isreleased from the shoulder' 18 and deposited in anysuitable receptacle The arm 4 in moving upward is moved out; wardly byreason Yof the inclined face of the notch 19 riding over the'pin 8, soas to permit the coin G passing bet-Ween the lower end of the arm 4 andthe shoulder 18 on the 'arm 5. The moment the coin G is released frombetween the shoulder 18 and the arm 4, the latter is moved back into itsnormal position by means of the plate spring 10, thereby re-positioningthe `pin 8 -below the shoulder 13 onl the arm 4 in such a position as toprevent the operation of the lock until another coin has been deposited.

From the foregoing it is seen that the arms 4-5 in conjunction with theescutcheon plate A and back plate 14 and shoulders 16*18 constitute ineffect a slidingpocket for the coin, 'through which pocket the coin Visadvanced step by step positively; first,

when engaged by the pusher 17; 'and secondly', by the engagingof theabutment 16 -behind Athe coin, the arm 4 yielding toward and from arm 5suiicient to accomplish the desired purpose.

Having thus described my invention, what I vclaim and desire to secureby Letters Patent is- 1. In a coin-controlled lock, the combination of alatch bolt, a barrel for reciprocating the same, a key for turning thebarrel,

f ment formed on the other arm.

2. In a coin-controlled lock, the combina.- ton with a latch bolt, of abarrel connected therewith to move the bolt, a key for operating' thebarrel, coin-controlled mechanism permitting of but a single completereciprocation of the bolt on 'the deposit of a single coin, saidmechanism including va pivoted plate connected with the barrel :torsliding movement, a pocket formed with said plate,

Van opposed co-acting wedge-shaped abuty ment, between which and saidsliding plate a coin is adapted to be held, and means carred by thesliding plate for advancing the l coin past said abutment.

3. ln a coin-controlled lock, the combination with a sliding latch bolt,of a key-operated barrel for actuating,` the bolt, a pair of oppositelysliding arms connected with the barrel and reciprocal thereby, meansco-acting with the arms to inclose a coin pocket, said arms having alimited yielding movement toward and from each other, and meanscoperating with the arms by which the key is normally held againstwithdrawal from the barrel.

4. ln" a coin-controlled lock,`the combination-with a sliding latchbolt, of a key-operated barrel for actuating` the bolt, a pair ofoppositely sliding arms connected with'thev i barrel and` reciprocalthereby, means co-acting with the arms to inclose a coin pocket,

said arms having` a limited yielding movement toward and from eachother, means cooperating with the,VKV arms by 'which the key is normallyheld against withdrawal from the barrel, and means in conjunction withthe arms whereby, upon deposit of the coin, the bolt may be projectedinto locked position and 4the key withdrawn and subsequently the boltretracted by the key, whereupon the key assumes its normal positionagainst withdrawal until the deposit of another coin.

5. The combination with a latch bolt, oit a barrel having a lug tooperate the bolt, a key to operate the barrel, and coin-controlledmechanism including; a sliding coin v pocket connected with the barrelto allow the latch bolt to be operated only on the deposit of a propertoken.

6. In a lock, the combination of a turnable key-actuated member, a pairof arms pivoted to the ,member on opposite sides of the center, a coinpocket formed by said arms, detent means for preventing the rotation ofthe member until the deposit of a coin in the pocket, and releasemechanism controlled by the coin.

7. In a coin-controlled lock, the combination of a rockable membercontrolled by a key, a pair of parallel arms connected with saidrockable member, means for limiting the movement of the rockable member,means for supporting` a coin between said arms, and means whereby thecoin Will act lo permit an increased movement of the roekable member.

8. ln a coin-controlled lock, the combination of a pair of parallelarms, a pivoted member to which said arms aie attached on opposite sidesof the pivotal point, means for limitingr the movement of the pivoted'member, and means controlled by a coin between said arms for permittingan increased movement of the rockable member.

9. In a coin-controlled lock, the combination of a pair of parallelreciprocating members, a rockable plate for reciprocating said memberscontrolled by a key, means for supporting a coinl between said members,means for limiting the movement of said members and the rockable plate,and means whereby an initial movement ot the rockable plate will co-actwith the coin to permit e an increased movement of the rockable plate.

10. ln ay coin controlled lock, the combination cfa pair ofreciprocating members, means for reciprocating said members in oppositedirections, a stop for one of said members, and means controlled by acom for renderingsaid stop ineffective to limit the movement of saidmember.

ll. In a coin controlled lock, a pair ot oppositely disposedreciprocating members having a limited movement toward and Yfrom eachother, a push bar carried by one of said members, a cam `face upon theother of said members directed toward said push bar, a coin chute fordelivering a coin edgewise between said push bar and said cani tace, andmeans for reciprocating said members in opposite directions to grip saidcoin between said push bar and said cam face to separate the saidmembers.
